Title: Preparation of package having no failed wire
Inventor: KIN KAZUO
IPC: H01L21/60
Filed: 1995-06-09
Abstract: PURPOSE: To prevent a defect in wire, such as wire sweeping or a short circuit, by covering a package entirely with a coating material after a wire bonding step is carried out. CONSTITUTION: A coating material like perylene dimer is entered in an inlet opening and fed to a vaporizing chamber 11 through a line L4. The coating material is heated by a heating means at the vaporizing chamber 11. The perylene dimer gas is transported through a line L3 and heated at a heat decomposition chamber 12. The decomposed perylene monomer gas is fed to a coating chamber 13 and sprayed to a wire-bonded package at the coating chamber 14 to form a conformal coating film. As a result, a defect in wire, such as wire sweeping, a wire drop or a short circuit can be prevented.

Title: Battery testing method
Inventor: SEKINO YOSHIHIRO
IPC: H01M10/48
Filed: 1981-09-11
Abstract: PURPOSE:To perform the measurement with a high reliability agaist the variance of the voltage of a battery and the resistance of a load, by connecting a current source and a testing load in parallel between both terminals of the battery to be tested and controlling the output current of the current source to adjust the discharge current of the battery. CONSTITUTION:A current iB from a battery 4a to a load 11 is adjusted to a prescribed level to make the discharge test under constant conditions possible. When the resistance value of the load 11 is denoted as R and the voltage of the battery 4a is denoted as EB' the voltage EB is indicated by expression, and the voltage EB and the current iB are lowered when the battery is left as it is. Therefore, a current iC is reduced by a value corresponding to the lowering of the discharge current iB to make the current iB constant. For the purpose of performing this adjustment, the discharge current iB is detected by a sensor 8, and a current source 9 is so operated automatically that the output of the sensor 8 is constant; and thus, the current iB is kept constant even if the resistance value R of the load 11 is changed by temperature. The accumulation capability of the battery 4a is discriminated on a basis of the magnitude of the current iB and a time (t) required for discharge of the overall capacity.

Abstract: PURPOSE:To detect the magnitude and the direction of oscillation, by irradiating  the light to photodetectors, which are arranged one-dimensionally, through an  optical mask, where the pattern which changes the incident light in accordance  with the oscillation input is formed. CONSTITUTION:When an oscillation is applied to a casell, an oscillation system mass 12 is moved relatively to the case 11, and the pattern of the light of a light source 2 which is transmitted through an optical mask 13 to reach a  photodetector array 14a of a photo detecting array circuit 14 is changed.

Abstract: PURPOSE:To ensure stable printing process without electrolytic corrosion of an electrode, even if energized for a long time by allowing either one of an ink ejection device or an ink storage device to be aged in ink and thereby forming a high resistance film. CONSTITUTION:Ink 1 consists of fatty acid such as paraffin wax, carnauba wax or behenic acid molten thermally at a ratio of 1 to 60 wt.% and nigrosine black dye molten likewise at a ratio of 1 to 8 wt.% in a mixture with the former. In addition, 1 to 15% of slipacks PSI is added as an electrically conductive material for formation of a film to the ink 1. Further, a direct current is applied using a drive power supply 11 and thereby an aging phenomenon is caused by energization at a constant voltage. Thus a film 16 is formed at the interior of an ink jet head 2 and on the surface of an oscillator 6. Subsequently, the surface of a material which constitutes the ink jet printer head is not eroded by ink and also is not corroded due to electrolysis by forming a stable, highly electrically resistant film 16 on the surface using an aging in-ink technique.

Title: Instruction fetching control system
Inventor: OZAWA YOSHIHIRO
IPC: G06F9/38
Filed: 1991-05-21
Abstract: PURPOSE:To improve the branching action performance in an electronic computer equipped with a processor and a cache to perform the instruction fetching by the burst transfer of a fixed word unit. CONSTITUTION:When a branching control circuit 16 decodes an instruction extracted by a multiplexer 15 and detects the branching, the circuit outputs the branching instruction to a pre-fetching control circuit 14. A branching destination address calculating circuit 17, when the branching instruction is outputted from the multiplexer 15, sets the branching destination address to a branching destination address register 11. The pre-fetching control circuit 14, when the branching instruction is added, sets the branching destination address to a pre- fetching address counter 12 and outputs a cycle starting signal CST to instruct the fetching start. Thus, an address latch circuit 21 holds the branching destination address from the pre-fetching address counter 12 and a transfer control circuit 23 transfers the instruction shown by the content of the address latch circuit 21 stored in a memory 24 to a processor 1.

Title: Power supply control system
Inventor: UCHIDA KATSUMI
IPC: G06F1/00
Filed: 1983-08-10
Abstract: PURPOSE:To facilitate the duplicating and multiplexing in the structures of a power supply controller and to improve the reliability of a power supply system, by controlling the power supplying state in response to a CPU for a device whose power supply is controlled. CONSTITUTION:When the application of power supply is indicated by power supply controllers 1-1-1-m respectively, a power supply application indicating signal 13-1 is turned on. At the same time, signals 14-1-14-n corresponding to the designated central processing identification numbers are turned on together with AND gates 15-1-15-n. Then corresponding FF17-1-17-n are set to obtain a power supply application mode. In the same way, a power supply breaking indicator signal 13-2 is turned on together with AND gates 16-1-16-n turned on to a power supply breaking indication. Then the FF17-1-17-n corresponding to the relevant CPU are reset to cancel the power supply application state. However either one of the corresponding FF17-1-17-n is set continuously as long as either one of CPUs which are not designated. Therefore, the output of an OR gate 18 is turned on to continue a power supply application state. This means that the application is still available with other CPUs.

Title: Electromagnetic contact device
Inventor: FURUKAWA KUNIYUKI
IPC: H01H50/54
Filed: 1988-06-13
Abstract: PURPOSE:To reduce shock at the time of striking against a fixed iron core by providing a bridge member to be inserted in an aperture where a contact support is not inserted into a movable contact and a load level control spring for energizing the member. CONSTITUTION:A bridge member 14 made of e.g., plastic reinforced by glass fiber is inserted in an upper aperture 3a of a contact support and it is compressed by a contact spring having a suitable property as a load control spring against a partitioning member 3c between the upper and lower apertures. When a movable iron core 4 is attracted through the electrification of an solenoid coil 6, force in a counter-attraction direction is largely decreased in a play stroke until the member 3c is brought into contact with a movable contact 11. However, when the member 14 abuts against the back side of a fixed contact 9, load by the spring 13 is applied to a conical compression spring. As a result, excessive energy retained is reduced and shock at the time of striking to the fixed iron core is therefore reduced, so mechanical and electrical performance is improved.
